A final update about my situation.
After many frustrating e-mails with Audeze customer service I decided to send a FB message to Sankar Thiagasamudram. I got an answer at 5 o'clock California time, asking for my e-mail address and told me that I will have a solution to my problem by the end of the day. I got a second reply in the afternoon detailing all the parts that have been shipped with fed-ex.
That was on the 4th of June.
Today the parts were delivered to me:
After one month of sitting in the box I have a perfectly straight pair and I can finally listen to music.
I have to say that the customer service was disappointing in every aspect as not only they were not fast, but even when I got an answer it was not a satisfying one.
If I got the quality of service that I got after talking to Sankar it wouldn't be such a frustrating experience.
Some inside details that might concern some of you:
"Regarding the bent yoke, we had a 60 day period where the supplier made a mistake in using a softer material in manufacturing the headphones. Your unit's manufacture date falls within that period. We have since then resolved that matter."
Manufacture date was 6-4-2014. That's April, it's Europe style date.
Also a video from Audeze with the Yoke kit replacement instructions.

Finally, the proper in case placement also from Audeze:
I hope that was the end of the problems for my pairs and I can finally enjoy them.
